Honest Concurrent Use Under Section 12: When India Permits Two Identical Trade Marks

Indian trade-mark law is generally one mark, one owner, one class. Section 11 of the Trade Marks Act, 1999 lays down the relative grounds for refusal — an identical or similar earlier mark blocks the later application. But the Act carries a structural exception that resolves a recurring practical problem: two parties who, in genuinely separate good-faith trade activity, adopted the same or similar mark independently. Section 12 of the Act gives the Registrar discretion to allow registration of identical or similar marks where the case of honest concurrent use or other special circumstances is established. The doctrine is unusual, narrow, and frequently misunderstood — but it is the structural exit valve for parallel-trade situations where neither party is in the wrong.

This guide explains what Section 12 actually permits, what the Registrar looks for in deciding whether to allow concurrent registration, what restrictions can be imposed, and when the doctrine is the right tool for an Indian applicant facing a Section 11 refusal.

The text of Section 12

Section 12 of the Trade Marks Act, 1999 provides that the Registrar may permit the registration of identical or similar trade marks for the same goods or services, or for the same description of goods or services, by more than one proprietor, where the Registrar is satisfied that there has been honest concurrent use or other special circumstances which make it proper to do so. The Registrar may impose such conditions and limitations as appropriate — typically including limitations on use to specific geographies, channels of trade, or product variations.

The discretion is the Registrar's. The applicant carries the burden of establishing the case for concurrent use, and the evidence requirements are substantial.

Two honest traders. Same mark. Different stories. Section 12 is the door.

What counts as 'honest concurrent use'

Indian courts and the Trade Marks Registry have applied a multi-factor test that examines:

1. Duration of use — substantial parallel use, typically measured in years rather than months
2. Quantum of trade — meaningful commercial volume on both sides, not token use
3. Geographical separation — different regions of operation reducing the likelihood of consumer confusion
4. Honesty of adoption — both parties adopted the mark in good faith, without knowledge of the other's prior use
5. Public confusion — actual evidence of confusion in the market weighs against concurrent registration
6. Public interest — would denying concurrent registration cause disruption to established businesses?

The leading test traces back to the English Pirie's Application decision (1933), which has been adopted and refined by Indian courts in multiple decisions. The five Pirie factors — extent of use, area of use, degree of confusion likely, honesty of adoption, and inconvenience that would be caused — remain the operational reference.

When Section 12 is appropriate

Three fact patterns frequently produce Section 12 outcomes:

• Regional businesses with parallel pan-India histories — two regional businesses that grew independently in different parts of India and only encountered each other when both expanded into a national market
• Family or branch separation — successor businesses arising from a partition or split of a family enterprise, where both branches genuinely carry the original mark
• Independent adoption of common dictionary words — two businesses that adopted the same descriptive or common-dictionary term independently in different segments of trade

The procedure

An applicant facing a Section 11 refusal may invoke Section 12 in reply to the examination report. The reply must:

• Set out the factual case for honest concurrent use — dates of adoption, geography, channels, volumes
• Annex documentary evidence — invoices, sales-tax/GST returns, advertising bills, press coverage
• Address the lack of confusion in the market — affidavits from trade and customers may be filed
• Propose any limitations or conditions the applicant accepts (e.g., geographic restriction, channel restriction)

The Registrar typically calls the matter to a hearing where Section 12 is invoked. The earlier-mark proprietor may participate. The order is reasoned and appealable. Where granted, the registration usually carries express limitations.

Limitations and conditions

Section 12 grants almost always come with conditions. Common limitations imposed:

• Geographical limits — registration limited to specified states or regions where the applicant has historically operated
• Channel limits — registration limited to specific channels of trade (e.g., wholesale only, specific retail formats)
• Product variations — registration limited to a specific sub-class or product variant where the prior mark covers a broader range
• Distinguishing features — registration conditional on the applicant adding a distinctive identifier (e.g., a geographical suffix) to disambiguate from the senior mark

Section 12 vs Section 34 (prior-use defence)

Section 34 protects a continuous prior user against a later registrant. Section 12 is different: both parties seek registration; the Registrar permits both to coexist on the Register. The two work together — a prior user with the strongest Section 34 evidence can invoke Section 12 to obtain registration alongside the conflicting mark, rather than relying on the unregistered defence.

Strategically, where both rights coexist in practice, Section 12 registration is preferable to a Section 34 defence — registration provides statutory infringement standing, customs recordation eligibility, and a defined geographic and class scope.

Coexistence agreements

Many Section 12 matters resolve through a coexistence agreement between the senior and junior users, filed with the Registrar in support of the application. The agreement sets out the agreed limitations, geographic and channel divisions, and confidentiality and dispute-resolution terms. Registrars typically welcome coexistence agreements as they reduce the consumer-confusion risk and document the parties' agreement on how to operate alongside each other.

For brands that have evolved through independent histories — Indian regional businesses scaling nationally, family-business splits, parallel-imports companies — the coexistence agreement combined with Section 12 registration is the durable solution.

The takeaway

Section 12 is a narrow but important Indian trade-mark provision. It accommodates the reality that two honest traders can independently arrive at the same or similar mark without any wrong on either side. The doctrine is evidence-heavy and the Registrar is cautious, but the framework allows parallel registration with appropriate limitations. For Indian businesses facing Section 11 refusals on genuinely-independent parallel histories, the section is the structured route to coexistence.
